The Solid State Drive The solid state drive is a solid-state storage device. Unlike the normal hard drives or Floppy discs because the SSD has no moving pieces. They are much faster in latency and access time compared to the regular HDD drive but they are also higher in cost. Some new SSDs can even surpass 4 Terabytes of memory. There are also now new drive which use the best part of both SSDs and HDDs combined called Hybrid Drives or SSHD. The SSD also is like an over glorified usb stick as they are similar in structure.

History
SSDs were founded around the same time as magnetic core memory. They emerged during the eras of vacuum tube computers though, they stopped being used after drum memory units were cheaper and better. In the 1970's and 1980's they were used in certain IBM, Amdahl and Cray computers but, they were used uncommonly because of the high price point for them. To this day we still sometimes use SSDs because of its incredible speed increase from regular HDDs.

Memory The memory of SSDs mainly consists of NAND flash memory. It is chosen over DRAM memory because it is cheaper and dosn't need constant power supply to retain its memory. These NAND flash memory cards are slightly slower than DRAM and earlier models were sometimes even slower

than HDDs but, overtime the technology got better and better and now they are still slower than DRAM but exponentially faster than HDDs.
In this video a man explains what the differences of HDDs and SDDs.
In this video a man tests the amount of stress SSDs and HDDs can take.
